To all 'zc/0m it may concern:

Be it known that l, JIM O. TURVAN, citizen of the United States-I residing at Fort Griiiin, in the county of Shackelford and State oi Texas, have invented certain new and useful Improvements in Automatic Railway-Gates, of which the following is a specification. l i This invention relates to new and useful improvements in railway gates. y y n The object of the invention is to provide a swinging gate and automatic means of particular construction for operating the gate; said means including a rail arranged to be depressed by the engine and so held while the train is passing whereby the gate is elevated.

Another object of the invention is to provide a device of the character described that will be strong, durable. eiiicient, easy of operation, and simple and comparatively inexpensive to construct, also one in which the several parts will not be likely to get out oiy working order.

lilith the above and other objects in view the invention has relation to certain novel ieatures ot construction and operation, an example of which is described in the following specification and illustrated in the accompanying drawings. wherein:

Figure l is a perspective view ofthe invention and a portion of a railway track. the open position oi" the gate being indicated in dotted lines. and Fig. 2 isa cross-sectional detail of the tripping rail and component parts.

In the drawings the numeral l designates an elongated cross tie on which the gate is mounted.. A post Q is secured to each side of the tie and carries a trunnion 3 at its up per end on which a gate 4l is pivoted. The gate normally projects horizontally across he track at substantiall7 right angles to the rails A and B and rests in a seat 5 projecting from a latch post 6.

Along the inner side of the rail A a tripping rail 7 is disposed and extends a considerable distance on each side of the gate. The ends of the rail 7 are inclined downward at each end and terminate in depending lugs 8 slotted to receive pins 9 which limit the upward and downward movements ot' said rail. At intervals angular guides l0 are engaged under the rail A and receive the tripping rail as shown. Opposite each guide a filler block 1l is fitted under the -head of the rail A and against the web and 'has its `outer yt'ace flush with the side of the rail head. By this construction the tripping rail is prevented from tilting laterally 'a'ndfis given a free channel in which to work. y rit the end* of the tie l adjacent the rail A a lever 12 has its end pivoted on theside of said tiey and extends under the rails to a point beyond the post 2 where it is pivoted rto the lower end of a link 13. The linkhas its upper end pivoted to the gate, eccentricallyl with relation to the trunnion 3. It is obvious that the lever when depressed or swung downward will pull down on the link which will exert this force on the gate, where the latter will be swung upward or elevated as shown in dotted lines in Fig. l. The gate is not swung to a true perpendicular position but arrested at a slight angle.

The pivoted end of the gate is rounded to facilitate swinging' as shown.

:it the end of the tie adjacent the post 2 an upright 17 is disposed at an angle so as to incline toward the gate and is held by a pair of braces 18 which are also secured to the tie. The rounded end of the gate eX- tends between these braces which act' to steady it in Vits operation. At the upper end Vof the upright a plunger 20 is mounted and normally extended bv a spring 19 coiled tliereabout between the upright and the head of the plunger. Wfhen the gate is elevated a notch 2l engages the head of the plunger and forces the same back or into the upright, thus cushioning the elevation of the gate and tending to force the gate downward when released.

Over the lever l2 the tripping rail 7 carries a depending shoe l5 which rests on a boss extending upward from the lever. When the rail is depressed the shoe rides on the boss and swings the lever downward as indicated in dotted lines in Fig. l. Thus when the engine of a train approaching in either direction nears the gate, the flanges ot the wheels ride onto the rail 7 and depress the same, wherebv the gate is elevated as described. The rail 7 is long enough to operate the gate in advance of the train and to hold it elevated until the rear extremity has passed. When pressure on the rail 7 is relieved the gate by its own weight and the pressure of the plunger 20 will swing down thus restoring the parts to their normal position.

The operating parts are few in number and of simple construction. The invention is o presented as including all modifications and changes as conne within thel scope ofthe appended claim. Y Whatl I claim, is:

' In a railway gate structure, the combina-V tionof an Aelongated base, a pair of posts having theirlower ends secured to the sides of the base, a gate normally overhanging the base and having one end pivotally mounted between the upper end of the posts, a depressible lever disposed along one side of the i 'base and having its swingingvend projecti' Go'piesofthis patent may be obtained for ingpast the posts, a depressible tripping .w raildis'posed over and resting on the lever adjacent the pivot point `or the'latter, a vertical link pivoted at its lower Lend to the 'swinging end of the lever and having its upper end pivoted to the gate above the pivot point of the latter, an upright mounted on the base and inclined towardy the pivoted end of the gate1 a pair of braces extending from the4 base to the upright and between which thepivoted end ofthe gate projects, and a 1 spring pressed plunger mounted on the up- .nM o. TURVAN.
